The Wasp filter has plus and minus CV inputs. The CGS matrix mixer has plus one way and minus the other controls too. So it is sort of covered. With my design I keep the attenuators separate from the modules so I can mix the CV levels with mixers or use simple passive attenuator and stack some bananas. This is in the spirit of Moog modulars.

You say you possibly send the ADSRs into the VCO. Have you thought of using a couple of these, one for each VCO?

After doing some tests with the light purple vinyl and the black text i decided on the orange colour for better contrast of the text & dials.

After getting home from the printers shop with 2 prints of the panel (it was quicker to do the drill template the same colour) , the good finishing print is lying in wait for the drilling to start over the weekend

A quick pic of the drill sticker'd aluminium sheet sitting in the wooden case.

First job, use a center punch & hammer and center dent all the crosshairs.
then gave the front a spray with drill cutting oil and drill the 230 odd holes with the stand drill at 3mm , that does the fixing holes top & bottom and a pilot hole for all the others.
Then 6mm bit for the toggle switches and pilot for pots n sockets.
8mm bit for the pots.
10mm for the rotary switches.
11mm for the sockets.

Peeled off the oily smeared template sticker then
sanded with fine grade P1000 wet'n'dry on the front and a rough sanding on the back.
Quick spray of automotive carb cleaner and wiped all the dust & grit away,
Then i washed the panel with warm water and washing up liquid and applied the good sticker , you can use a can of adhesive de-activator or a little soapy water to allow adjustment of the lineing up.

Next job , take a craft knife blade and slice out the holes and leave the panel for a couple of days to let the few air bubbles contract.

Hi , slowly coming together, been chipping away after work , built the noise circuit from the mfos ultimate on stripboard, some buffers to distribute cv's & gates to different areas of the synth , and ive stripped down 2 vco's / 2 vcf's & 2 ADSR's from the main modular , need to lengthen the wires going to the new panel.
Also sorted out my wedge case power supply.

The power supply.
I have totalled up the current needed on +12v line and -12v line and i need 550mA / 420mA respectively , i built a mfos adjustable power supply with just the regulators & volt adjust area of circuit , i have a large diy Raw DC power supply that powers the whole modular system , the rectified and smoothed DC from the main power station distributes to multiple regulator busbars which usually have 8 to 10 modules per busbar inside my main blue system.

All of this orange new synth is +/- 12V , keeps things simple

here is a pic of each of the main 12V 1.5A regulators on 150mm long alum "L" bar and a smaller "L" bar for the 9V 1A regulator which supplies the Behringer FX600 & RAT distortion.
The green sockets are 3pin (+12 / 0v / -12) and the stripey long lead is +9V.

The switch at the side is a double pole rocker , power switch to break the incoming +/- Raw DC.

I am awaiting the final PCB from the Bridechamber, a CS80 board. In the mean time I have just filled a couple of Fonik Henry Thomas 555 envelopes. Unfortunately I have run out of my scraps of Molex connectors etc etc so I have just put in a Rapid order. Also because I need some vatrols and odd chips an order has gone in to Farnell........

These are ADSRs you can loop and turn into LFOs and they have an LED for each stage....mmmmm.....lights

Of course with MTA type power connectors there are the headers for this and a crimp tool. I am filling up with different crimp tools. Do I need them? Sort of, they make life a lit easier and I like a tool

I also try to avoid the eBay chip purchase but sometimes this cant be done, especially as some of the module designs stick with the older chips from the original design. 3080s in the EDP Wasp filter as still pretty easy to get but the 3280s for the CS80 filter are a little more rare. And I do want to get one that works!! _________________http://soundcloud.com/for-mash-get-ash

Couple of silly faults found only on my veroboard circuits .... 2 surplus isolator holes , bridged now and a resistor leg in the wrong hole, fixed now , and a red faced moment when the 6 lfo's were pulsing crazily and randomly , yes, i had not connected the 0V ground tail wire for all the pots to 0V at the supply , deary me , heh , nevermind .
Here is another pic at the latest stage , getting busy round the back of the panel now.

2 more boards fixed in , a Ken Stone burst generator , hooked it up to the scope after no-chip test & "is the chip/chip's getting hot" test , passed both and it seems to be bursting with trigger pulses quite good , and the other board is the level converters for the stompbox fx circuits.
Next job , de-box & dismantle a Behringer FX600 pedal & transplant into the synth , this and the Rat distortion have to be patched on the panel , i thought about hard wiring them but there was room for sockets

How are the boards supported? It looks like it might be a lot of weight on the larger boards if they are only supported at the front._________________JacobWatters.com

Hi Jake , the boards don't flex when it sits in the box ( i've peeked inside with a torch , i was curious last week ) , each has 2 fixings per board to the bar , there is not a huge weight in a populated board and the wiring acts as soft brace , it will never go on the road because it's power supply comes from the blue monster's substation

FX dismantle & wiring this weekend .
I have taken the pcb out of the stompbox case and it looked quite difficult to take the pots off the manufactured pcb without damaging tracks so, i decided just to snip the pot legs with cutters , leave the pots in place but not connected and run wires from the snipped legs sticking up from the pot thru holes and sleeve them with heatshrink , this allows me to re-assemble the stompbox if i ever need to , unlikely .

All the pots are 47K , easy job , but the fx type selection is operated by a pot , im going to change this to a rotary switch with resistors between the poles to emulate the fx select pot action.

I connected all the power connections and hooked up to the modular supply's Raw DC output yesterday , No magic smoke , hurrah , had 5 trips from studio to soldering workbench to fix several little errors on my part , only 1 of my veroboard circuits playing up , the mfos micro-sample n hold , i robbed an LF444 from my soundlab++ to try it out , great triggers coming from it , but a rather lame cv with no stepping , i'll take a look at all my tracks with a magnifying glass , likely a sliver of copper somewhere , or something else silly.
Left the synth running for 3 hours yesterday and i do need some air flow around the 12v heatsinks , trip to the local DIY store for a couple of 50mm round, push in air vents & try to find the 50mm holesaw in the work van.
